IMlIlTAIlJJIC RIM FOR MOLDED RECEPTACLES.

Application led July 3,

To all 107mm. #may concern:

Be it known that I, ROBERT S. GROGAN, .a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Metallic Rims for Molded Receptacles, of which the fol` lowing is a specification. Y

The main objects of this invention are to provide an improved form of metallic rim for molded receptacles, such as concrete laundry tubs, trays, sinks, and the like; to provide a rim of this kind having an 1mproved construction and arrangement of telescoping parts to permit adjustment of the rim; and to provide an adjustable metallic rim which is simple in construction and adapted to be readily assembled.

An illustrative embodiment of this invention is shown in the accompanying drawings, wherein Figure 1 ,is a perspective view of a tub having one of the improved rims applied thereto.

Fig. 2 is an enlarged fragmentary planof one corner of the rim.

Fig. 3 is a bottom view of the same.

Fig. 4 is a transverse section taken on the line 4 4 of Fig. 2, and showing also part of one wall of the tub.

Fig. 5 is an enlarged fragmentary perspective view of one corner of the tub, showing the rim applied thereto. l

In themost common forms of adjustable rims "for molded receptacles heretofore in use, eachof the rim sectionshas been provided with interlocking portions, such as tongues and slots. formed adjacent the ends thereof and arranged so that the tongues of one side section were adapted for engagement with the slots of an adjacent side section. The formation of the interlocking portions directly on the side sections necessitatedthe cutting of these sections to the exact lengths required for each particular receptacle to which the rim was applied, and inasmuch as these receptacles varied in size. it wasnecessary for the receptacle manufacturer to carry a large stock of rim sections of various lengths. Moreover, such finished rim sections. could not be triu'nucd to a 1924. serial No. '724,169.

smaller size without the necessity of altering the position of one of the interlocklng portions of such sections.

In the specific construction herein shown, the present invention is applied to a rim wherein the main side sections aresecured together by corner sections which telescopically engage the ends of the side sections. The corner sections are all substantially. identical in construction and are adapted for use with all of the var-ious sizes of rims. IVith this improved rim construction, the side sections may be rolled out or otherwise formed in long strips, which may then be cut to the desiredlengths.

In the form shown in the drawings, the improved rim comprises side sections 1 and cornersections 2 telescopically arranged so as to initially-permit a relative adjustment of the rim sections. As illustrated, the rim' is applied to the upper edges of a concrete tub 3.v

The sections 1 and 2 are preferably sheet metal stampings, which may be cut and formed in a single operation. Each of the side sections 1 comprises an upper face 4, which is substantially the same width as the walls of the tub, and a depending flange 5 forming an outer side face which lies flat against the walls of the tub. Extending inwardly from the faces 4 and 5, are flanges 6 and 7 respectively, which are embedded in the material of the receptacle walls, so as to anchor the rim sections to the receptacle.

The corner sections 2 include upper faces 8 and outer side faces 9, which embrace the corresponding faces 4 and 5 of the side sections, and inwardly extending flanges 10 and 11 which embrace the corresponding flanges 6 and 7 of the side sections and which are also anchored in the walls of thel tub, The opposed ends of the faces 9 are recessed, as shown at 12, so as to eliminate any sharp edges at the corners of the tub and topresent a finished appearance.

.In molding the receptacle, the sidcl sections l'and corner sections 2 are assembled and placed at .the bottom of the mold in an inverted position, so that the concrete which is poured'into the' mold will force the side sections downwardly into firm contact with 'the corner sections. The inwardly extending flanges 6, 7, 10 and 11 become embedded in the concrete and anchor the rim to the tub. By this improved rim construction, the tele-scoping sections are firmly Secured togetherwithout the use of solder, rivets or other similar fastening means.

Although but one specific embodiment of this invention has been herein shown and described` it will be understoodthat numeroils details of the construction shown may be alteredi or omitted Without departing from the spirit of this invention as defined by the following claim.

I claim:

The combination with a molded receptacle, of a polygonal rim comprising side sections', corner sections telescopically enasto be anchored in the material of the re ceptacle, the flanges of said corner sections embracing the flanges' of said side sections.

Signed at Chicago this 30th day of June 19241.
